Separate and/or simultaneous generations of non-linear functions inherent in non-ohmic resistivities

In this paper, it is described that a multiple-function generator can be realized without employing any separate function-generating units and selector-logics. According to this proposal, a uniformly continuous non-linearity o f a non-ohmic resistance is first expressed by a linear combination of several interesting non-linear functions with respect to the same input variable. Then, the desired functions can be obtained by summing up algebraically the linearly independent non-linear currents passing through every non-ohmic resistance with their proper weights. It is noticeable that an adjustment of the weights will permit different non-linear functions separately and/or simultaneously. Details of this system will be furnished with quantitative investigations and experimental results.
